Description

Technical Field

[0001] The utility model belongs to the technical field of optical imaging, and in particular relates to an automatic cover-turning gel imaging device. Background Art

[0002] The gel imaging device is mainly used for nucleic acid gel imaging and analysis. The system provides ultraviolet light source, the system's built-in imaging software is used to take pictures, and then the image analysis software is used to analyze the taken images.

[0003] The gel imaging system commonly used for obtaining gel images is a dark box type photographic device, which has a structure of a transmission ultraviolet light source at the bottom of the dark box, and an immovable stage immediately above, which is used to place the gel block to be tested, that is, an upward shooting structure for shooting from top to bottom. The stage is a frame with a glass plate that can transmit ultraviolet light fixed in the middle. The ultraviolet glass plate can filter out clutter and only allow ultraviolet light of a certain wavelength to pass through. When using the instrument, pull out the stage, place the gel block on it, and then push it back, and stop it through the contact between the front plate of the frame and the dark box body. The charge coupled device (CCD) set on the top of the dark box takes pictures to obtain the gel image stimulated by the ultraviolet light source, and then transmits the obtained gel image to the computer.
